Northwest Africa 8014 (NWA 8014)

Northwest Africa

Purchased: 2013 May

Classification: Ungrouped achondrite

History: Purportedly found at the same site as NWA 7325 and other such stones near Bir el Abbas, Morocco. Purchased by Naveen Jain in May 2013 from a dealer in Zagora, Morocco.

Physical characteristics: A dense, dark green stone (210 g) with patches of pale green fusion crust. The interior consists mainly of bright green grains and pale gray grains with a peculiar "frosty" appearance.

Petrography: (A. Irving and S. Kuehner, UWS) Medium grained, microgabbroic igneous rock composed of calcic plagioclase, diopside and forsterite with accessory Cr-troilite, Ni-poor kamacite and rare grains of eskolaite, Cr-bearing Fe metal, suessite and K-Fe sulfide (possibly rasvumite). Plagioclase exhibits anomalously low birefringence, and contains abundant tiny, rounded inclusions of Cr-troilite and kamacite (especially adjacent to diopside grains. Diopside exhibits two sets of planar shock twin lamellae, and olivine grains have irregular, rounded shapes (with sinuous "moat-like" cavities along some margins).

Geochemistry: Olivine (Fa2.2-2.3, Cr2O3 0.4 wt.%), clinopyroxene (Fs0.8-0.9Wo44.7-44.3, TiO2 0.02-0.03 wt.%, Al2O3 2.8-2.9 wt.%, Cr2O3 1.0 wt.%).

Classification: Achondrite (ungrouped). This stone is paired with NWA 7325.

Specimens: 23 g and one polished thin section are at UWB. The remainder is held by Mr. N. Jain.
